petulant

And the public is petulant, demanding more of the same, but losing interest if you don't evolve.

Obama has his own share of hits against Trump, mocking him as a petulant, grievance-filled narcissist in his convention speech, while Michelle accused him of benefiting from the “affirmative action of generational wealth.”

Part and parcel of their impunity is a petulant refusal to be accountable for their partners’ actions, when those activities cast the justices’ own fairness into doubt.

In social media salvos as the trial opened, Cohen used a scatological nickname for Trump, taunted him to “keep whining, crying and violating the gag order, you petulant defendant!” and commented acerbically on his defense.

Certainly no medical expert would defend narcissistic behavior like violent outbursts, malicious deception or petulant refusals to admit defeat.
